What is the earliest time that a control can be focused on without causing an exception/server error? It seems that newly-created (in codebehind) controls cannot be focused on until they're added to the page (or another container on the page), but I'd like to confirm and make sure.
View 2 RepliesSo what I have is a bunch of dynamically created textboxs that when the user enters some data and either tabs out or clicks out some calculations are done. After the page posts back control focus is lost. What I need is to be able to set focus back to the control that was tabbed to or clicked into not the control that data was entered into.

I was having a discussion with a co worker about some controls I implemented. He objected to my use of dynamicly instantiating controls in the code behind, because it will be slower than specifying the control in the markup. I thought he was talking about output cacheing which to my understanding only caches the rendered output of a page not the instantiated Page object. He said no its a different type of caching. Unfortunately he was unable to give me any documentation to backup the claim so I am wondering if anyone here has ever hear of any such type of caching, and if so is there any documentation on it that I can refer to.
View 5 RepliesI am working on a web form using VS 2010. The controls I've added previously to this form will show in the drop down list in code behind and are available to add events too. However any new controls I've added for last week or so are not visible in the list. I cannot access their events. I have scoured the forums and tried everything I can think of, nothing works.
View 5 RepliesI have written this in my source page
<script type="text/javascript">
function CloseMe()
{
window.close();
}
</script>
and in code behind after clearing the sessions i have this
ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(), "CloseMe();", true);
The page is closing, but it gives a confirmation dialogbos saying do you really want to close this page Ok and Cancel. I don't want this confirmation box to come i just want the page to close how can i go about doing that.

I have a page with an iframe on it in which I load another page.On this iframe page I have some textboxes above eachother.When the first textbox is filled with a code the textchanged event is called nd the code is checked with the database.After the code has been changed to the right one (if needed) I want the focus to go to the next textbox.
So at the end of the event I do: Page.SetFocus(txtbox2)ut after the postback refresh, the focus is gone.
I have also put the control to be focused in a session variable and then in the page_load event I set the focus to the control in the session variable, but still no focus on the textbox.How can I put it on the 2nd textbox?all is done in the Iframe page codebehind.
I need this focus because the two textboxes are filled via bar code reader and after the scan an "enter press" is done automatically and to be able to allow two scans after each other this focus change is needed.
I am creating an ASP.NET website in Visual Studio 2010 (.NET 4.0) in C#.
I have a user control applicant_information.ascx which contains text boxes.
The page application.aspx contains this user control:
<%@ Register src="controls/applicant_information.ascx" tagname="applicant" tagprefix="uc1" %>
<uc1:applicant ID="applicant1" runat="server" />
The application.aspx page contains a multiview, and the applicant1 user control is in one of the views. The button continue takes the visitor to the next view which contains another user control of text boxes.
I want to write validation code on the continue_Click event which is in the application.aspx.cs page. Ideally, from the application.aspx.cs code behind page, I want to get the user input from a text box in applicant1.
Intellicense cannot seem to find any of the text boxes in applicant1 from application.aspx.cs.
